7.62mm Lee-Enfield No.4 (L8 / Sterling Conversion) Low Shooting: An Experiment 

In my personal experience, many wartime produced .303 barrels are out of spec, with bores slugging .314 - .315 usually, sometimes as high as .319. Add that to the cordite ball ammo that was once used and that accounts for 4 - 6 MOA rifles. North American produced Number 4s tend to have barrels with better tolerances, but again 3 - 4 MOA. In spec, post-war FTRd No. 4s with 5 groove barrels typically shoot 3 - 4 MOA with ball. Although with the right handloads I've gotten them down to under 2 MOA. But if you're shooting real groups (10 shot groups), because of the barrel profile and lack of bedding you should expect something in the range of 3 MOA with good handloads normally. Unless you're taking over 10 minutes to shoot a 10 shot group and let the barrel cool. My brief encounter with a No. 4T and handloads was quite pleasant. 1.5 MOA group, just under 2 MOA second group with handloads. No. 4s can shoot as well as the typical Garands, Mausers, Mosins and Springfields of the era. But wartime spreewerke barrels tend to paint a different picture (2 groove US barrels aren't exciting with 10 shot groups either). The L39/L42 heavy barrel upgrade does make a difference. If you had a similar weight barrel in .303 I have no doubt you would get good accuracy. The L42 is still a capable weapon and would perform well as a DMR. No, it's not a blueprinted Remington 700 or SAKO TRG, but it doesn't cost as much either. And with the right optic and good handloads in the right hands it will get the job done out to 500M every day.

Fascinating. Really illustrates how many factors are in play when you're discussing the accuracy, or lack thereof, of any given rifle.

More Enfield nerdery, just what I came for. Keep it up old chap!

I was just about to ask "why are you single loading", and then you went ahead and explained it... ;)

Bloke Your are just increasing my interest in these old rides. So much history and so cool. Thanks

I love the experiments on the range mikey

Always a learning experience with Enfields & BotR

It's almost like the shooter is just as important at the rifle. Knowing how to shoot with your rifle is how you really achieve precision, accuracy.

Excellent video. I remember reading about and watching a different video on Lee Enfield rifles having some goofy barrel harmonics, especially with lighter barrels; hence the application of pressure at certain points of the barrel to either deaden or redirect the harmonic vibrations.

Excellent thanks Bloke. For me this video nicely complements my recent visit to a famous museum, where I was allowed to hold both a No.4 and a No.1 but was not allowed to manipulate them in any way, for health and safety reasons. As a classically trained target shooter, I was taught to always check that firearms were unloaded, as the first action on being handed one, and I seen such checks prevent at least two unfortunate events.

I like the timestamp to jump past the shooting, as if anyone who's watching this isn't here for the meticulous nerdery of every round fired. Thanks for the content.

Any video with a Lee- Enfield in it is an interesting video.

Way more than vaguely interesting. No. 4's as target rifles will always been an interesting journey.

I own one of these sterling conversions with the bolt guide cut to allow the removal of the bolt. the first time i shot it the front piece of guide rail ripped clean off. havent shot it since but it is a convenient conversion as someone who loves the lee action and primarily uses the 308 cartridge.

8:30 empty cartridge ejected into the box of ammo, that made my day 😄

Interesting, I haven’t any experience with a conversion… thank you!

I was shooting no 4s when I was ten in the army cadets then the Bren loved them 1960s

Took my 7.62mm No4 Mk1 to Blair yesterday, blade foresight, AJP rearsight and Norma ammo from 1982. 72.4 at 500 yards. High maggie was a result of snow in the eye and the inner was just a typical Blair curveball.

Aloha; well done! Keep up the great work. Mahalo

Hi, thanks for this excellent video, please make a video showing the bedding is on that L39A1 rifle, these kind of videos are very informative for other fellow Lee Enfield pattern rifle owners, cheers!

Have 1926 lithgow with near new heavy barrel...will shoot almost moa all day , also have aia no4 mk4 in 7.62 and accuracy is incredible....never been a fan of no4 rifles due to the light barrel...built a no4 with 10 rd ak mag shortened no4 barrel in 7.62 x39,must be my favorite lee enfield...good luck.

What Enfield owners and Mosin owners have in common: packing random stuff around parts of the barrel to get better accuracy. Fascinating as always!

Great review and there’s a cool way about you. Have you seen 9 hole reviews? Maybe try a similar concept to those guys, that would be fun.

Very interesting.

I recently acquired an 1955 made n.4 MK2. Out of the box it shoots perfectly, but to stay in the middle of the target at 100 meters with S&B standard .303 I must hold the rear sight at 450 yards.

Returning to the music track background i think the archers theme covers this episode....tum tee tum tee tum😁

I got a good chuckle at the "Ouch" over 10 rounds, and remembered back to the days of shooting 200 rounds of 7.92x57 in a day. Perhaps this is why one of my collar bones is significantly larger than the other... (This belongs to this clip no idea why it shows up on the Ruby pistol one. Or why this video says it's only 1 hour old to me, but comments already 2 says old...)

8:28 Ejected right back into the box, lmao!

I have in my collection a No4 mk1 T, a No4 Mk2, an M1 Garand made by Breda, a 1903 Springfield Mk1 and an M41b, I sold my M96 for the space on my licences for the M41 b. Of all these well preserved rifles. The Swedish M41b is the most accurate. I was in a 300m competition shooting a borrowed K31 recently, and my co shooter was the guy who bought my M96. I had a great first round with the K31, second round not so good. My co shooter shot amazingly in the second round with the M96. Shot my best score and was ahead by 5 points. The guy who won was 40 points ahead, also with an M96. The 6.5x55 along with the 7.5x55 round seems to be the best rounds for 300m prone shooting here in Ireland at the moment.

Greetings from NT in Australia. Love the all your videos. Without starting a brawl, can you shoot commercial 308w hunting ammo out these old Enfields chambered in 7.62? Relatively familiar with 303s not so 7.62s. I have the following. Martini 303. Mk1 Long Lee. 2x SMLE Lithgow WW2 era models Savage No4. Lee Speed. Regards, Dave.

Nice

Huzzah! Reminds me of shooting my 8mm and being beat about.

Very interesting...

Could you possibly do a range test on the Ishapore 7.62 2A1 Lee Enfield ? It's one of my favorite rifles !

You keep reminding me how badly I want an L39 and an L42...

Who says No.4s are not accurate? At age 16, I shot a 33/35 at 500 yards, 2 2 3 5 5 5 5 5 5, the two outers: I destroyed a spotting disk, I under corrected my sights and then proceeded to destroy another five spotting disks in the bull. That was with a .303! Admittedly that was with target sights. When I owned my own target rifle, it was a 7.62mm conversion of a No.4 ( I spent all of 250 quid on that) and it performed pretty much as well as one of my follow club members 2000 quid rifle!

I have been out of the shooting world now for 15 years would love to start again did it fot 30 years probably now to old 67

After the Second World War a lot of Lee Enfields were converted to .410 shotguns and I have even seen one converted to 9mm Flobert which must have required some firing pin modifications to fire a rimfire.

Hey Bloke, if you have the time for handloading, try surplus dm111 147gr bullets with 41gr N140 . For whatever reason my no4 7.62 conversion groups fantastically with it. Has a similar V0 than mk7ball

14:07 -- "Lets see what this does and where it goes" ..... all over the place as expected. I had heard that people did try "sporterizing" No 4 and "floating" the barrels, and the results were always bad. And if this conversion has a lighter barrel, I'm not surprised. The barrel harmonics of the unsupported barrel had to have been flinging the rounds all over the place. I didn't think this test would show a drop, my gut feel is it's a barrel harmonics issue. Either due to a change in the weight of the barrel, of the speed at which the propellent of the newer NATO cartridge produced a different harmonic on the barrel, so even while it was bedded in the same manner, the barrel's not pointing in the same direction when the round leaves.

I've got one of these! Currently making it into a No FauxT as someone had tried to do it in the past and gave up.......(it already has the cheek piece and the receiver is drilled and tapped for No 32 - just badly)

Very interesting, I have a quick question, I recently acquired a No4 mk2 1955 still in the wrap, should I unwrap it? And if I do what will remove cosmoline but not damage the suncorite finish? Thank you for the info and all of the great videos!

S&B makes the best ammo for the money, period.

sounds like "jump is what we in the States call barrel harmonics. if you shoot different loads you get a different aim point if its all quality ammo groupings should be similar.

I do like the L39 - if I were so inclined to subject myself to the pain in the arse that is the UK's firearm ownership rules - that would be a rifle I could see myself having. However I am very content to watch the Bloke enjoy it. I bet the dynamics of the No. 4's skinny barrel and wood bedding is really quite complicated. I'm sure you've explained this before but are the barrel bedding pressure points there to add an anti-banana effect to counter the barrel going banana-shaped under pressure? Were the Sterling conversion barrels basically just 303 barrels with 7.62 chambers cut into them or were they specially made? The bullet diameters seem so close that I can imagine someone thinking "it's at the low end, but it's within tolerance" and running with existing tooling to cut the barrel/rifling. Probably talking out of my arse but I wonder if additional clearance around the bullet would have an amplifying effect on any error in the barrel bedding - i.e. if the barrel has gone more banana shaped than it should due to over or under-compensation from the bedding, the bullet can strike the wall of the barrel harder because it has more clearance to accelerate in, causing the POI to shift.

It's resonance and harmonics.

Mike,There is an idea called editing to be able to stitch things together. As we get older (as we are) the recoil gets sharper into your shoulder. There is less meat in your shoulder to soak up the ft./lbs that old girl is giving you! snicker, my problem as well. BTW, I have 2 enfields. No.1 & No.4; what is the count of yours. I know you shoot more than I do I think I've seen 5 or 6 Enfields on your vids. Later, Matt in No. Tex.

I wonder if the original.303 barrel shooting fine with Mkvii ammo means that the people who made the guns and the ammo possibly might have known what they were doing 😮

Hi, somewhere in the old back ups of my memory banks (1950’s) I seem to remember the trials with Bren Gun barrels being used to produce a Snipers rifle. True or false? Cheers mate. Harera

Now do it for an ishapore 308!!

Years ago, I shot with a fellow club member who had one of these, fitted with a scope. It was known as an Enfield Enforcer. He beat the pants off me, I was using a 308 Ruger with hand loaded ammo.

Wow... Nice... No clue what it is but I think I would like it. Can you say a bit more about what an. L39 is??? That tells me nothing since I never heard of it. I'm sure for many that's all they need to know what is being talked about Ah.. ok.. I got a bit more info.. the whole model.. L39A1

Hey Mike, slightly off topic, but do you hand load any of your centerfire ammo, or do you just run commercial/market available surplus?

It would've been really strange if a faster projectile was shooting significantly lower, so this isn't super surprising, but it's good to confirm.

The L4A4 Bren conversion was a questionable idea , as a .303 chambered weapon it was flawless however everyone that I used chambered to 7.62 nato would jam quite often

It should be about the same as the 303 Enfield. The only difference is the powder really. The change in burn characteristics could be the cause of the groups. A new stock or glass bed the old stock should settle the old girl down.

Try it with a Ishaphore 2A1. Mine shoots 1.5 moa. Barrel harmonics causing difference.

So did you happen to trade away the proper sight on the rifle, or did you happen to have a different one at some point?

Do these shoot worst then the Ishapore 2A1 rifles?

Conclusion ? The whole 7.62 NATO conversion should have been : everything to 303 British .😅

Is Switzerland soon going to ban guns like here in Australia can you still own a semi auto and full auto over there?

Do you reload your own ammunition? Are you aware of what barrel harmonics are and how they effect accuracy, which is optimised with powder weight in the reloading process, which is why every rifle barrel is individual. This also reinforces the effect of a fully floating barrel. The Americans are big fans of barrel tuners. Cheers,

Were the Srerling conversions or the L39s imported to the US?

Why no rear bag? I would think you would be getting shooter fatugue

modern bolties may be better but man, id kill for a MADE TODAY No.1 MK.3 with all the bells and whistles but in 308

"Real Money" lol

Why not load the mags .Many years ago we never loaded individually To help keep your aim ???

The parker hail conversion looks to be a really good shooter. i wonder how it would be with handloads. The sterling conversion look good enough for government work.

If that doesn't work well... I'll.... TAP TAP TAP TAP... A other example.. An you please let me know what that is supposed to mean???

I hate math!

your cork is too big.. "that is what she said"

Ill keep saying this until it sinks in. The No.4 Rifle is not a Lee Enfield. It is simply an Enfield. James Paris Lee's name was dropped at the introduction of the redesigned No.4, as every single part of the design had been changed.

Manufacturers velocity numbers are really meaningless, shot from a test rifle, one needs to measure that from the rifle it is going to be shot from. Having chronographed ammunition shot in my rifle and compared that to of what the manufacturer or that matter load book specifies very seldom are they close.

Swallow your pride and get a cheap slip on rubber recoil pad. You'll thank yourself

Knowing things in Advance? Sounds like cheating to me 🙂

You need to cut out the panting audio..sounded like Jimmy Savile waiting to get onto a children's ward..

The barrel didn’t half move inside the furniture with just your hand!!!
